ISAAC LAPIDUS, OF BROOKLYN, NEW YORK.

LOCK.

To all whom it may concern Be it known that 1, Isaac LAPIDUS, a citizenof the United States, residing at Brooklyn, in the county of Kings andState of New York, have invented new and useful Improvements in Locks,of which the following is a specification.

This invent-ion relates to locks and more particularly to coincontrolled locks for use in connection with patent coat boxes, lockers,and other public compartments used for storing articles of personalwear, baggage, or the like.

The principal object of the invention is to provide a device of thischaracter wherein the bolt operating key is secured in the lock againstremoval until a coin of the proper denomination is deposited in thelock, at which time, the key holding means will be thrown to inoperativeposition and the key may be operated to throw the bolt and also may beremoved and retained by the party depositing the coin or check.

A further object of the invention is the provision of a coin controlledlock wherein the coin is inserted directly into the lock casing insteadof in the slot leading to the casing or external mechanism forcontrolling the bolt, whereby when the door is actual! in lockedposition, the coin can not be inserted or the lock operated in anymanner eX- cept by the party holding the key.

Another object of the invention is the provision of a device of thischaracter having means for locking the key cylinder and the key withinthe lock casing, together with coin controlled means for releasing thekey locking means, which key locking means is placed in operativeposition to again lock the key and key cylinder when the bolt isprojected so that when the bolt is retracted to unlock the locker, box,or other device to which the lock is attached, the key and key cylinderlocking means will automatically operate to prevent further operation ofthe device until another coin is inserted.

Further objects of this invention will appear as the following specificdescription is read in connection with the accompanying drawing, whichforms a part of this application, and in which Figure l is a frontelevation. Fig. 2 is side elevation of the lock with the closing plateremoved. Fig. 3 is a similar view showing the coin inserted and parts inunlocked position. Fig. a is a similar view.

showing the parts in position after the bolt has been projected. Fig. 5is a detail horizontal section taken through the key cylinder. Fig. 6 isa detail vertical section taken through the money drawer. Fig. 7 is aperspective view of the key cylinder removed. Fig. 8 is a perspectiveview of the coin discharging plate.

Referring more particularly to the draw ing, 1 represents an ordinarylock casing having a closing plate 2 secured over the casing by means ofthe screw 3 which threads into the central pivoting stud 4-. Slidablymounted in the casing and adapted to be projected through the opening 5and the front plate 6 thereof is a bolt 7 which is guided in itsmovements by lugs 8. The bolt is provided as is usual with a boss 9which is engaged on either side of the lug 10 formed upon the pivotedkeeper member 11 held in engagement with the bolt beneath the spring12.The bolt is provided with the usual notch 13 which is adapted to beengaged by an upstanding lug 14 carried on the arm 15 and the keycylinder 16. This key cylinder is adapted to receivea fiat key 17 havingan aperture 18 formed therein which registers with a similar aperture 19formed in the key cylinder. The key cylinder is provided, as is usual,with the limiting arms 20 and 21 which abut against the bolt and limitthe forward and rearward movement thereof.

Pivotally mounted upon the central piv oting stud 4 is a curved arm 22having an attenuated end adapted to pass through the slots 19 and 18when the bolt is in retracted position to the key cylinder stoppedagainst rotation by reason of the engagement with the arm 20 with thebolt. This arm 22 is normally held in such position by means of a leafspring 23 and is thrown to inoperative position by a check or coin whichis adapted to engage a depending finger 24 formed integrally with thearm. When a check or coin is passed through the slot 25 in the frontplate 6 and forced against the finger 24, said finger will be carriedbehind the end of a locking spring 26 secured to a lug on the frontplate 6. When this finger has been operated upon by the coin and the arm22 thrown to inoperative position, the key cylinder may be rot-ate d bythe key until the bolt is in locked position when the keymay bewithdrawn and re tained by the depositor of the coin until it is desiredto remove the articles placed in the locker.

In order to disengage the end of the spring 26 from the end of thefinger 24;, there is provided a sliding plate 27 having a dependingfinger 28 and a diagonal slot 29 which is engaged by a pin 30 carriedupon the bolt 7. The plate is normally moved in a direction so that thefinger will engage the spring 26 by a leaf spring 31 so that when thebolt is projected, the spring 31 and the pin traveling in a diagonalslot 29 will force the finger 28 into engagement with the spring 26,release the same from the end of the finger at, and permit the spring23, to throw the attenuated end of the arm 22 into engagement with thekey cylinder.

Slidably mounted through an opening 32 formed in the front plate 6 is amoney re ceiving drawer 33 having a latching bolt 34 rotatably mountedtherein and provided with lugs 35 adapted to be engaged by a spring 36.This spring is thrown out of engagement with, the lugs by the key whichenters the bolt for turning thesame so that when the key is forced intothe bolt, the spring will be released from thelug and the bolt will bepermitted to turn with the key.

What is claimed is 1. In combination, a casing, a sliding bolt mountedtherein, a rotatably mounted key cylinder having a slot thereinand'abolt operating arm, key having an aperture adapted to register withthe slot in the cylinder, and means for engaging the slot in thecylinder and aperture in the key for locking the cylinder againstrotation and the key against removal from the cylinder.

2. In combination, a casing, a sliding bolt mounted therein, a keyrotatably mounted in the casing and having an aperture and a boltoperating arm, pivoted means spring operated for engaging the aperturein the key cylinder to prevent the cylinder from rotating, means forthrowing said pivoted means to inoperative position, means for lockingthe pivotedrmeans 1n inoperative position, and means actuated on theprojec- 7 tion of the bolt for disconnecting the'locking means.

3. In combination, a casing, a sliding bolt mounted therein, a rotatablymounted key cylinder having a SlOt therein and a bolt operating arm, akey having an aperture adapted to register with the slot in thecylinder, means for engaging the slot in vthe cylinder and apertureinthe key for locking the cylinder against rotation and the key against"removal from the cylinder, and means for releasing the key and cylinderlocking means.

4. In combination, a casing, a sliding bolt mounted therein, a keycylinder rotatably mounted in the casing and having an aperture and abolt operating arm, pivoted means spring operated for engaging the slotin the key cylinder to prevent the same from rotating, means forthrowing said means to inoperative position, means for locking thepivoted means in inoperative position, and bolt operated means fordisconnecting said locking means.

In testimony whereof I afliX my signature in presence of two witnesses.
